The American Christmas Tree Association say prices for artificial trees rose 10% to 15% this year due to the new tariffs. On a recent December day, Mark Latino and a handful of his workers spun sheets of vinyl into tinsel for Christmas tree branches. They worked on a custom-made machine that’s nearly a century old, churning out strands of bright silver tinsel along its 35-foot (10-meter) length.Latino is the CEO of Lee Display, a Fairfield, California-based company that his great-grandfather founded in 1902. Back then, it specialized in handmade velvet and silk flowers for hats. Now, it’s one of the only companies in the United States that still makes artificial Christmas trees, producing around 10,000 each year.
